Re: Pro/Cons for Sigma 12-24 II & Canon 16-35 II

Your corrected sample doesn't show much “loss of picture estate” but the original is not so badly distorted either. Was the picture taken at 12mm? Thanks for taking the time to post them!

The image below was downloaded from the samples posted in the review of Sigma 12-24 II at lenstip.com (http://pliki.optyczne.pl/sig12-24II/sig12-24_fot09.JPG)

Notice the loss of picture space is quite severe after applying the corrections. I know it’s probably the worst case scenario with parallel lines at both edges of the picture. I wonder if 16-35 would do any better.

I know there's room for improvement in terms of correcting the above but it's beyond the point.

In your pictures you are not (only) correcting the lens distortion, but somehow the perspective (I don't know the exact name). That correction has nothing to do with the lens (unless you have a tilt-shift lens), so you will have to apply that correction anyway.
